Access Now.js and express.js from the web folder

Question

Where do I have to install Now.js and express.js to access it from the web folder?

My web-folder is located here: /var/www/virtual/domain.com/htdocs and I'm using node v.0.6.6

But when I install now.js with "npm install now" in the root folder, I get an error when I want to run my server.js file:

var html = require('fs').readFileSync(__dirname+'/index.html');
var server = require('http').createServer(function(req, res){
  res.end(html);
});
server.listen(8080);

var nowjs = require("now");
var everyone = nowjs.initialize(server);

everyone.now.distributeMessage = function(message){
  everyone.now.receiveMessage(this.now.name, message);
};

Error: Cannot find module 'now'

Do I have to set the node_path somewhere? Or do I have to place the now.js file into my webfolder?

Answer 1

NPM will install now and express in the folder where you are when you execute the install command. NPM will create a folder called node_modules and put them there. If you have a file you need to run named server.js, make sure it's at the same level as node_modules.

If you just want to install them locally and use them everywhere do it like so:

npm install now -g

The g flag stands for 'globally'.
